不同耕作方式及气候对土壤扬尘产生量的影响

The Impact of Different Cultivation Methods and Climate on Soil Dust Production

为探索不同耕作方式及气候对农田扬尘产生量的影响,在田间架设气象环境监测站记录一年的试验数据然后进行分析研究。试验设置4个处理组,结果表明,在4个不同处理组中,组2的PM2.5、PM10和TSP浓度显著高于组1、组4及组3;除组2以外,组1、组4和组3的月均PM2.5、PM10和TSP浓度依次递减;土壤温度、湿度及风速对4个处理组的PM2.5、PM10及TSP浓度影响均极显著。该研究为农田生产过程中降低扬尘产生量、选择合理耕作方式提供了数据支撑。

To explore the impact of different cultivation methods and climate on the amount of dust generated in farmland,a meteorological environment monitoring station was set up in the field to record one year of experimental data and then analyzed and studied.The experiment set up four treatment groups,and the results showed that among the four different treatment groups,the concentrations of PM2.5,PM10,and TSP in treatment group 2 were significantly higher than those in treatment group 1,treatment group 4,and treatment group 3;Except for treatment group 2,the monthly average concentrations of PM2.5,PM10,and TSP in treatment group 1,treatment group 4,and treatment group 3 decreased sequentially;The effects of soil temperature,humidity,and wind speed on the concentrations of PM2.5,PM10,and TSP in the four treatment groups are extremely significant.This study provides data support for reducing dust production and selecting reasonable farming methods in agricultural production processes.
